I have removed the LED Driver but did I burn the component next to it?

I have removed the LED driver on my Macbook Air because it needed to be replaced do to water damage (actually it was honey/syrup salad dressing).

I used a hot air station to remove the driver. Worked great and it came right off but I am worried that I ruined the component next to it on the left (U3210)

I have attached a picture. Here you can see that U3210 has brown gunk around it. This was sizzling and bubbling when I was removing the driver for backlight. Is this maybe just the sugar that was coming off (from the syrupy dressing)? Does this need to be replaced? How can I tell? Any input here would be helpful

After removing the driver, I wicked the pads and removed the excess junk with alcohol. Does this look decent? I am afraid that I ripped a pad off?

@rymiff try to clan the board some more. Either use some isopropyl alcohol and a soft brush or maybe you can get an ultrasonic cleaning done. Can you post another image just zoomed in a bit more? I assume your board is a 820-00165

@oldturkey03 Yes my board is 820-00165. I will attach a better picture shortly. Is it normal for an adjacent component to excrete moisture when heating another component? I will get in there and clean it up more. I originally used a q tip and alcohol and brown (rust like) liquid came up on the Q tip. Would it be possible that I melded the solder on U3210 and if so, does that mean it would have to be replaced? I will notify as soon as I post another picture in the original post

the brown stuff is called underfill they use it at the factory so solder doesn't get everywhere i think your fine

be careful with cleaning the pads they can break cuz they are held in with glue
